Oxygen cylinder sizes vary, but all are considered "full" when pressure equal to:</p><p>Your answer:</p><p>1,500 psi</p><p>2,000 psi</p><p>2,500 psi</p><p>1,000 psi</p><p>20.

The artificial ventilation techniques whose use in children is contraindicated unless the provider has had special training is:</p><p>Your answer:</p><p> two-person BVM</p><p> flow-restricted, oxygen-powered ventilation device</p><p> mouth-to-mask</p><p> one-person BVM</p><p>22.
